Analysis And Design Of Information Management And Decision Support System For Hairy Crab

In view of the current information management system for hairy crabs,this paper studies the demand of information security,hairy crab merchants,system users and hairy crab farmers in detail by means of field survey,questionnaire and scene simulation.It can be seen that the information management system for hairy crabs in the current market is not very mature,there are many problems.In this paper,starting from reducing technical cost and operation cost,improving information security and providing relevant decision data,the solution of the problem is studied and the design scheme is given.This paper completed the prototype design of the information management system for hairy crabs,through Axure prototype tool.And it provided requirements analysis use cases,business logic,function points,data dictionary and database structure diagram related to requirement model.And also it provided detailed design of common modules,security deployment architecture design,data security isolation design,data interface document design,system architecture and layering design related to software design.The system is mainly divided into four functional modules:WEB merchant module,client module,big data and auxiliary decision-making module,and back-end management module,and the four functional modules respectively deal with corresponding business.The system designed its own low-cost universal encryption module based on AES encryption theory and solved the security and cost problems of the system.By combining the operation data generated by the system with crawler crawling,interface acquisition and background input,and using visual graphics to directly see the methods recommended by experts,the problem of big data acquisition and auxiliary decision-making was solved at a low cost.Through the analysis of the actual demand,the system module was redesigned to make the software provider,merchant and farmer complete the related business requirements at the lowest cost.The system reduces the maintenance cost of the system through a reasonable design of software module.
